Furthermore, it means ensuring that this best practice model is actually delivered to patients and families.

The relative importance of these elements in relation to outcome has not yet been established.

This article outlines a framework for preventive intervention in early psychosis, based on more than a decade of experience initially gained within a first-generation model.

This experience has been followed, after a prolonged gestation, by the birth of the Early Psychosis Prevention and Intervention Centre (EPPIC), a comprehensive « real-world » model of care targeting the multiple clinical foci underpinning the preventive task.

Data are reported to illustrate the topography and impact of delay in treatment in our regional setting, and the results of an initial evaluation of the EPPIC model are presented. (...)
